Pest Control FAQs, answered by experts

Allowing wolf spiders to reside in your home can have benefits, as they serve as natural exterminators, preying on insects and pests that could become problematic. Their presence can help keep your residence relatively free of nuisance insects such as flies, ants, and cockroaches, reducing the need for chemical pesticides. Wolf spiders are generally not hostile towards humans, and their bites, although painful, usually don't result in a significant medical concern. If you can coexist peacefully with these spiders and recognize their role in maintaining a balanced ecosystem within your household, they can contribute to a healthier and pest-reduced environment.

DIY treatments exist, but professional extermination is recommended for thorough elimination and prevention.

Neither the black widow nor the brown recluse are deadly spiders, and North America has no deadly species. However, other places in the world do, including Australia, which is home to the funnel web spider, considered the world’s deadliest spider. However, Australia has not reported deaths from a funnel web spider bite over the past few decades after developing an antivenom.

Getting roaches to completely go away will take a lot of effort, and they hardly ever go away on their own. You will likely need a combination of home treatments, like roach sprays and traps, and regular visits from an exterminator, to control an infestation. It can take awhile for these treatments to start working, and you’ll need to stay on top of replacing old traps and having additional extermination services, plus keeping your home clean and decluttered, to deter roaches.

It’s very uncommon for roaches to bite humans. Cockroaches don’t need humans for food and prefer to be elsewhere than on a living being. They have no poison or powerful pincers to cause any significant damage. However, in very bad infestations cockroaches have been known to search humans for dead skin cells, which leads to them nibbling around feet, hands, and eyelashes. They don’t cause any serious harm, but this is an easy way to spread the diseases cockroaches carry.
